  Fix #8956. ValueError message was only mentioning one signal.

  Rather than list out the three signals (or more over time), the message was
  made less specific but still descriptive.

Jean-Paul Calderone b33f0c1ccd Revert r60115
This revision introduced quoting for strings containing | based
on a misunderstanding of the commonly used quoting rules used
on Windows.

| is interpreted by cmd.exe, not by the MS C runtime argv initializer.
It only needs to be quoted if it is part of an argument passed through
cmd.exe.

See issue1300, issue7839, and issue8972.

Victor Stinner 2b271f7e30 Fix regression introduced by r81154 (Issue #5099, subprocess destructor) 2010-05-14 21:52:26 +00:00
Brett Cannon 42a0ba7b2c subprocess.Popen.__del__ referenced global objects, which is a no-no thanks to
interpreter shutdown semantics. Same issue goes for the methods that __del__
called. Now all the methods capture the global objects it needs as default
values to private parameters (could have stuck them on the class object itself,
but since the objects have nothing directly to do with the class that seemed
wrong).

There is no test as making one that works is hard. This patch was
verified against a consistently failing test in Mercurial's test suite, though,
so it has been tested in some regard.

Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
Genellina for writing another patch for the same issue and attempting to write
a test.

Brett Cannon 3d6137962c Revert an accidental commit from r80492. 2010-04-25 23:11:51 +00:00
Brett Cannon 1994969c15 When DeprecationWarning was silenced by default, it also silenced any use of -Q
by default as well. This change fixes that by treating -Q like -3 when it comes
to DeprecationWarning; using it causes the silencing to not occur.

Fixes issue #7319.

Brian Curtin a2936cfa09 Fix #7838. Add docstrings and privatize _subprocess implementation details.
Since CREATE_NEW_* are used for the creation flags of a subprocess, they
were added to __all__. The rest of the previously exposed attributes are
now qualified by _subprocess.ATTR rather than importing *.
2010-04-24 15:40:11 +00:00
Brian Curtin e5aa886b44 Implement #1220212. Add os.kill support for Windows.
os.kill takes one of two newly added signals, CTRL_C_EVENT and
CTRL_BREAK_EVENT, or any integer value. The events are a special case
which work with subprocess console applications which implement a
special console control handler. Any other value but those two will
cause os.kill to use TerminateProcess, outright killing the process.

This change adds win_console_handler.py, which is a script to implement
SetConsoleCtrlHandler and applicable handler function, using ctypes.

subprocess also gets another attribute which is a necessary flag to
creationflags in Popen in order to send the CTRL events.

Amaury Forgeot d'Arc ce32eb7406 #6416: Fix compilation of the select module on Windows, as well as test_subprocess:
PIPE_BUF is not defined on Windows, and probably has no meaning there.

Anyway the subprocess module uses another way to perform non-blocking reads (with a thread)

Gregory P. Smith dd7ca24eb5 Use select.poll() in subprocess, when available, rather than select() so that
it does not fail when file descriptors are large.  Fixes issue3392.

Patch largely contributed by Frank Chu (fpmc) with some improvements by me.
See http://bugs.python.org/issue3392.

Candidate for backporting to release26-maint as it is a bug fix and changes no
public API.

Brett Cannon 03446c43ca Remove warnings generated for the suprocess module when run under -3. Required
commenting out True/False compatbility stuff, remove a use of apply(), and
remove a use of buffer() (just pulled the solution used in 3.0 which is direct
slicing).

Gregory P. Smith a36f8fefb0 - Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
argument in python 2.5, this broke code that subclassed Popen to include its
  own poll method.  Fixed my moving _deadstate to an _internal_poll method.

Gregory P. Smith 4036fd4b75 Fixes issue2791: subprocess.Popen.communicate leaked a file descripton until
the last reference to the Popen instance was dropped.  Adding explicit
close() calls fixes it.

Candidate for backport to release25-maint.

Christian Heimes e74c8f2879 Added kill, terminate and send_signal to subprocess.Popen
The bits and pieces for the Windows side were already in place. The POSIX side is trivial (as usual) and uses os.kill().

Gregory P. Smith 92ffc634e4 Undo an unnecessary else: and indentation that r60104 added.
try:

except:

the else: is unecessary due to the blind except: with a raise.

Gregory P. Smith 87d49792b5 Fixes issue1336 - a race condition could occur when forking if the gc
kicked in during the critical section.  solution: disable gc during
that section.  Patch contributed by jpa and updated by me to cover the
race condition still existing what therve from twistedmatrix pointed
out (already seen and fixed in twisted's own subprocess code).
